“…Moreover, the pulsating current in DC discharge is a common phenomenon under many other discharge configurations in various gases. In hollow cathode discharge (HCD) or parallel-plate discharge, the self-pulsing phenomenon has similar characteristics and may occur in almost all gases such as air, nitrogen, oxygen, argon and helium under proper conditions 25 – 28 . Periodic pulsating were also revealed experimentally in transversely homogeneous barrier discharges in helium at small values of the parameter Pd (below 500 torr · mm), which may relate to the negative differential resistance of the cathode fall region 29 .…”

We confirm in this paper that Trichel pulse of negative corona is a common phenomenon that can occur in various gases rather than only in electronegative gases as considered in the last 70 years since G W Trichel firstly reported. Trichel pulse is exactly a mode transition between low-current Townsend and high-current normal glow regime, two pulseless stages of negative corona with different operating conditions and ion flux threshold. The rising of the pulse corresponds to the breakdown and formation of temporal glow discharge, the decay corresponds to the destroy of temporal sheath, and the interval (or repetition frequency of pulses) is determined by the re-building of the positive ion cloud to enhance significantly the local electric field for glow discharge to form again. The positive ions play a predominant role for the pulse formation and the mode transition, while the negative ions in electronegative gas are not necessary even if they affect greatly the pulsing process.

“…For τvt = 200 μs only a small fraction of the vibrational energy is transferred to translational energy, since τvt is now comparable to the total simulation time. ) 13 10 shows the distributions of the reduced electric field and gas temperature on the symmetry axis for different values of τvt. The reduced electric fields are hardly affected by the value of τvt and they all decrease from about 950 Td to 10 Td for increasing distance to the tip.…”

“…For many years Trichel pulses were thought to only occur in electronegative gases. The relationship between the frequency and amplitude of these pulses and the voltage, electrode shape, pressure and humidity were studied [11][12][13][14]. In 2001, Akishev et al proved that the pulsed mode of a negative corona can also be observed in pure nitrogen [15].…”

“…In recent years, advanced sensing, data storage, and communication have extensively promoted and developed imaging techniques [6,7]. Researchers have already carried out optical imaging studies of gas discharges using imaging instruments such as intensified charge-coupled device (ICCD) cameras and streak cameras [8][9][10][11][12][13]. The literature [8] used the ICCD camera to count the branching angle, cross-sectional area, and other parameters of the channels under high-purity nitrogen and artificial air conditions and then studied the branching characteristics of positive streamers in different nitrogen-oxygen mixtures.…”
